I enjoy looking at Classic Audio for pricing and benchmarking what the different receivers are worth. I have found their prices to be pretty steep however. I have bought my units off ebay and have found great receivers for much less. I have a guy here in Houston who will service these for $55 a pop. He is my age (a remnant & survivor of the 60s-70s) so he not only enjoys working on them and does a great job but he apreciates the units and their sound. Yes, he is a blessing to have found!!!
